Abstract

While established best practices exist for the sizing and positioning of dental implants, there is a notable lack of guidelines tailored to assist clinicians in predicting primary implant stability in fresh extraction sites. Accurately forecasting an implant's surgical success is critical for clinicians for two primary reasons: First, it guides treatment decisions. If conditions for successful placement are suboptimal, alternative plans, such as site development, should be considered. Secondly, precise prediction of surgical outcomes fosters a strong doctor-patient relationship, as communicating a no, low, medium, or high likelihood of success is essential for maintaining this rapport.

This retrospective cohort study aims to evaluate the predictive value of the Five-Thread Guideline (5-TG), which posits that engaging at least five implant threads in native bone correlates with high primary stability. The study assessed four qualitative levels of stability probability: none, low, moderate, and high. Among the 150 cases analyzed, the 5-TG demonstrated significant predictive accuracy indicated by (p<0.0000207). Consequently, this guideline could be regarded as an essential tool for forecasting implant stability when planning dental procedures in newly extracted sites.
